FREIGHT-ELEVATOR.

SPECIFICATION forming part of Letters Patent No. 307,980, dated November11, 1884.

v 3 Application filed June 25, 1884. (No model.)

To all whom it may concern Be it known that I, CHARLES B. PAXTON,

of Vicksburg, in the county of WVarren and State of Mississippi, haveinvented certain new and useful Improvements in Freight-Elevators, ofwhich the following is a full, clear, and exact description.

The object of my invention is to provide a freight-elevator for loadingand unloading water-craft, especially at low stages of water; and itconsists in an adjustable platform and endless elevator combined, ashereinafter described and claimed. I

Reference is to be had to the accompanying drawings, forming part ofthis specification, in which similar letters of reference indicatecorresponding parts in both the figures.

Figure 1 is a vertical section and partial elevation of my improvedelevator, 2 is a side elevation of the same.

A is a vertical shaft stepped in a box, a, under or upon the deck of thevessel or other support.

B is a double-cogged master-wheel loose on shaft a, and supported by itshub resting on the step.

0 is a frame carrying the stage and elevator, and supported on the upperend of the shaft A by boxes in cross-bars b, that are keyed to the shaftor rest on shoulders thereon.

d is a vertical shaft sustained in bearings on frame 0. This shaftcarries at its lower end a pinion, e, engaging the internal cogs ofwheel B, and on its upper end is a bevel-pinion, f. I

g is a horizontal shaft on frame 0, carrying a bevel-pinion, h, meshingwith pinion f, and also carrying chain-wheels it for endless chains kis, that pass over similar chain-wheels, 'Z, on a shaft, Z, at the upperend of the stage D. The side bars of the stage D are hung on the shaft9, so that the outer end can be raised and inions n n that en a e inionso 7 b and Fig.

lowered. There is also a shaft, m, extending lengthwise of the stage andcarrying bevel- 0 on shafts 9 Z for the purpose of transferring thepower to the upper shaft, Z, and keeping the chains taut. The two chainsare connected by crossbars 10 at suitable intervals. This constructionallows the stage, with the elevating-chains,

to be raised and swung to the required height and position for the upperend to rest upon a dock or shore.

The elevator may be operated by stearnor other power, as mostconvenient; but usually the steam-capstan on the vessel will be gearedto wheel B, so that when set in motion the chains, with bars 0, will becaused to travel in either direction and carry up or down any freightplaced on them.

The wheel B may be keyed to the shaft A and the shaft fitted to revolve.I do not limit myself in that respect, nor in other details ofconstruction.

Having thus described my invention, what. I claim as new, and desire tosecure by Letters Patent, is-

1. In a freight-elevator, the combination of the stage D, carryingendless chains, the shaft 9, frame 0, and gearing, substantially asdescribed, for operating the chains.v

2. In a freight-elevator, the combination of the frame 0, carrying anendless-chain elevator, the shaft A, master-wheel B, and connections,substantially as described, for operating the elevator.

3. The shaft m and pinions n n o 0, combined with the chain-wheel shafts9 Z, chains k, chainwheels Z 'Z, and stage D, as and for the purposesspecified.
